Abstract

The invention discloses a device and a method for multi-information detection and fusion based on OPC (OLE for Process Control) technology. The device comprises a signal detection circuit, a monitoring computer and a control computer, which are sequentially connected together, as well as an OPC interface connected between the monitoring computer and the control computer and used for realizing communication. The device and the method for multi-information detection and fusion based on OPC technology can overcome the problem in the prior art that single information has shortcomings, and is likely to cause the defects of inaccuracy in measurement, low measurement precision, error accumulation and poor safety, and so on; multi-information fusion remedies the defects of single information so as to realize the advantages of being accurate to measure, being unlikely to cause error accumulation, and improving measurement precision and safety.

Description

technical field [0001] The present invention relates to the technical field of multi-information processing and control in high-speed rail train control systems, in particular to a multi-information detection and fusion device and method based on OPC (Object Linking and Embedding for Process Control) technology. Background technique [0002] In the high-speed rail train control system, speed control is one of the important indicators. my country's high-speed railway system generally uses the combination of wheel speed sensor and Doppler speed radar to measure the train running speed. Speed ​​sensors are more accurate at high speeds, and radars are more accurate at low speeds and when the wheels are spinning or slipping. Simultaneous use of these two devices for speed measurement can achieve complementary advantages and obtain a more accurate train speed than a single speed sensor. [0003] In order to improve the reliability of the speed measurement system, each set of veh...
